Ne4ueva [31]

Turn y - 4 = -2/3(x - 6) into a linear equation.

y - 4 = -2/3(x - 6)

y - 4 = -2/3x + 4

 +4                +4

y = -2/3x + 8

The equation that is perpendicular to y = -2/3x + 8 is y = 3x + 4 as shown in the image below using a graph.

What is the solution set of the compound inequality 8< 4 - x <10
lina2011 [118]
You can solve all together or separate.

so you do

8<4-x. subtract
-4 -4

4<-x divide
-1. -1

4>x

-4>x since you divide by negative the sign flips.

4-x<10
-4. -4
-x<6
-1 -1

x>-6


8<4-x<10
-4 -4. -4 subtract 4 on all 3
4<-x<6 divide -1 to all 3
-4>x>-6 you flip sign since you divide by negative.

By cutting away identical squares from each corner of a rectangular piece of cardboard and folding up the resulting flaps, an op
sp2606 [1]

Answer:

The maximum volume is: 11.52 *10.52*2.74  = 332.06 in^{3}

Step-by-step explanation:

Let x is the side of the square in inches.(x >0)

The volume of the resulting box when the flaps are folded up can be expressed as:

V  = x (17 -2x)(16-2x)

= (17x -2x^{2})(16-2x)

= 4x^{3} - 66x^{2} +  272x

To find the value of x which yields the maximum of volume (V), take the first derivative of this equation and set it equal to zero.

\frac{dV}{dx} = 12x^{2} - 66x + 272

Solve 12x^{2} - 132x + 272  = 0

<=> x = 2.74

The dimensions of the box are:

Length: (17 -2x) = (17 -2*2.74) = 11.52

Width: (16-2x) = (16-2*2.74) = 10.52

High: x = 2.74

So the maximum volume is: 11.52 *10.52*2.74  = 332.06 in^{3}
